that are being broadcasted around a phone in `wifi`. However, iOS cannot

record any broadcasting network due to API restrictions, therefore iOS

wifi data only exists in `sensor_wifi`.

**Assumptions/Observations:**
|
|
|
|
|
:::
|
|
|
|
|
|
|
|
|
|
Features can be computed by app, by apps grouped under a single category
|
|
|
|
|
(genre) and by multiple categories grouped together (meta categories).
|
|
|
|
|
For example, we can get features for Facebook, for Social Network Apps
|
|
|
|
|
(including Facebook and others) or for a meta category called Social
|
|
|
|
|
formed by Social Network and Social Media Tools categories.
|
|
|
|
|
|
|
|
|
|
Apps installed by default like YouTube are considered systems apps on
|
|
|
|
|
some phones. We do an exact match to exclude apps where \"genre\" ==
|
|
|
|
|
`EXCLUDED_CATEGORIES` or \"package_name\" == `EXCLUDED_APPS`.
|
|
|
|
|
|
|
|
|
|
We provide three ways of classifying and app within a category (genre):
|
|
|
|
|
a) by automatically scraping its official category from the Google Play
|
|
|
|
|
Store, b) by using the catalogue created by Stachl et al. which we
|
|
|
|
|
provide in RAPIDS (`data/external/`), or c) by manually creating a
|
|
|
|
|
personalized catalogue.
|
|
|
|
|
|
|
|
|
|
The way you choose strategy a, b or c is by modifying
|
|
|
|
|
`APPLICATION_GENRES` keys and values. Set `CATALOGUE_SOURCE` to `FILE`
|
|
|
|
|
if you want to use a CSV file as catalogue (strategy b and c) or to
|
|
|
|
|
`GOOGLE` if you want to scrape the genres from the Play Store (strategy
|
|
|
|
|
a). By default `CATALOGUE_FILE` points to the catalogue created by
|
|
|
|
|
Stachl et al. (strategy b) and you can change this path to your own
|
|
|
|
|
catalogue that follows the same format (strategy c). In addition, set
|
|
|
|
|
`SCRAPE_MISSING_GENRES` to true if you are using a FILE catalogue and
|
|
|
|
|
you want to scrape from the Play Store any missing genres and
|
|
|
|
|
`UPDATE_CATALOGUE_FILE` to true if you want to save those scrapped
|
|
|
|
|
genres back into the FILE.

|
|
|
iOS Activity Recognition data labels are unified with Google Activity
|
|
|
|
|
Recognition labels: \"automotive\" to \"in_vehicle\", \"cycling\" to
|
|
|
|
|
\"on_bicycle\", \"walking\" and \"running\" to \"on_foot\",
|
|
|
|
|
\"stationary\" to \"still\". In addition, iOS activity pairs formed by
|
|
|
|
|
\"stationary\" and \"automotive\" labels (driving but stopped at a
|
|
|
|
|
traffic light) are transformed to \"automotive\" only.

|
|
|
|
|
|
|
|
In AWARE, Activity Recognition data for Google (Android) and iOS are
|
|
|
|
|
stored in two different database tables, RAPIDS (via Snakemake)

|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
Barnett's location features are based on the concept of flights and
|
|
|
|
|
pauses. GPS coordinates are converted into a sequence of flights
|
|
|
|
|
(straight line movements) and pauses (time spent stationary). Data is
|
|
|
|
|
imputed before features are computed. See Ian Barnett, Jukka-Pekka

**Assumptions/Observations:**
|
|
|
|
|
|
|
|
|
|
*Types of location data to use*
|
|
|
|
|
|
|
|
|
|
Aware Android and iOS clients can collect location coordinates through
|
|
|
|
|
the phone\'s GPS, the network cellular towers around the phone or
|
|
|
|
|
Google\'s fused location API. If you want to use only the GPS provider
|
|
|
|
|
set `location_to_use` to `GPS`, if you want to use all providers (not
|
|
|
|
|
recommended due to the difference in accuracy) set `location_to_use` to
|
|
|
|
|
`ALL`, if your Aware client was configured to use fused location only or
|
|
|
|
|
want to focus only on this provider, set `location_to_use` to
|
|
|
|
|
`RESAMPLE_FUSED`. `RESAMPLE_FUSED` takes the original fused location
|
|
|
|
|
coordinates and replicates each pair forward in time as long as the
|
|
|
|
|
phone was sensing data as indicated by `phone_sensed_bins` (see
|
|
|
|
|
`Phone valid sensed days <phone-valid-sensed-days>`{.interpreted-text
|
|
|
|
|
role="ref"}), this is done because Google\'s API only logs a new
|
|
|
|
|
location coordinate pair when it is sufficiently different in time or
|
|
|
|
|
space from the previous one.
|
|
|
|
|
|
|
|
|
|
There are two parameters associated with resampling fused location in
|
|
|
|
|
the `LOCATIONS` section of the `config.yaml` file.
|
|
|
|
|
`RESAMPLE_FUSED_CONSECUTIVE_THRESHOLD` (in minutes, default 30) controls
|
|
|
|
|
the maximum gap between any two coordinate pairs to replicate the last
|
|
|
|
|
known pair (for example, participant A\'s phone did not collect data
|
|
|
|
|
between 10.30am and 10:50am and between 11:05am and 11:40am, the last
|
|
|
|
|
known coordinate pair will be replicated during the first period but not
|
|
|
|
|
the second, in other words, we assume that we cannot longer guarantee
|
|
|
|
|
the participant stayed at the last known location if the phone did not
|
|
|
|
|
sense data for more than 30 minutes).
|
|
|
|
|
`RESAMPLE_FUSED_TIME_SINCE_VALID_LOCATION` (in minutes, default 720 or
|
|
|
|
|
12 hours) makes that the last known fused location won\'t be carried
|
|
|
|
|
over longer that this threshold even if the phone was sensing data
|
|
|
|
|
continuously (for example, participant A went home at 9pm and their
|
|
|
|
|
phone was sensing data without gaps until 11am the next morning, the
|
|
|
|
|
last known location will only be replicated until 9am). If you have
|
|
|
|
|
suggestions to modify or improve this imputation, let us know.
|
|
|
|
|
|
|
|
|
|
*Barnett\'s et al features*
|
|
|
|
|
|
|
|
|
|
These features are based on a Pause-Flight model. A pause is defined as
|
|
|
|
|
a mobiity trace (location pings) within a certain duration and distance
|
|
|
|
|
(by default 300 seconds and 60 meters). A flight is any mobility trace
|
|
|
|
|
between two pauses. Data is resampled and imputed before the features
|
|
|
|
|
are computed. See this paper for more information:
|
|
|
|
|
<https://doi.org/10.1093/biostatistics/kxy059>.
|
|
|
|
|
|
|
|
|
|
In RAPIDS we only expose two parameters for these features (timezone and
|
|
|
|
|
accuracy). If you wish to change others you can do so in
|
|
|
|
|
`src/features/location/barnett/library/MobilityFeatures.R`
|
|
|
|
|
|
|
|
|
|
*Significant Locations*
|
|
|
|
|
|
|
|
|
|
Significant locations are determined using K-means clustering on pauses
|
|
|
|
|
longer than 10 minutes. The number of clusters (K) is increased until no
|
|
|
|
|
two clusters are within 400 meters from each other. After this, pauses
|
|
|
|
|
within a certain range of a cluster (200 meters by default) will count
|
|
|
|
|
as a visit to that significant location. This description was adapted

This is just a quality control check, and if set to TRUE, a new column is added to the output file with the number of minutes containing location data that were used to compute all features.

For fused location, a single minute can contain more than one coordinate pair if the participant is moving fast enough.
|
|
|
|
|
sampling_frequency Expected time difference between any two location rows in minutes. If set to \'0\', the sampling frequency will be inferred automatically as the median of all the differences between any two consecutive row timestamps. This parameter impacts all the time calculations.

**Assumptions/Observations:**

|
|
|
|
|
|
|
|
*Types of location data to use*
|
|
|
|
|
|
|
|
|
|
Aware Android and iOS clients can collect location coordinates through
|
|
|
|
|
the phone\'s GPS, the network cellular towers around the phone or
|
|
|
|
|
Google\'s fused location API. If you want to use only the GPS provider
|
|
|
|
|
set `location_to_use` to `GPS`, if you want to use all providers (not
|
|
|
|
|
recommended due to the difference in accuracy) set `location_to_use` to
|
|
|
|
|
`ALL`, if your Aware client was configured to use fused location only or
|
|
|
|
|
want to focus only on this provider, set `location_to_use` to
|
|
|
|
|
`RESAMPLE_FUSED`. `RESAMPLE_FUSED` takes the original fused location
|
|
|
|
|
coordinates and replicates each pair forward in time as long as the
|
|
|
|
|
phone was sensing data as indicated by `phone_sensed_bins` (see
|
|
|
|
|
`Phone valid sensed days <phone-valid-sensed-days>`{.interpreted-text
|
|
|
|
|
role="ref"}), this is done because Google\'s API only logs a new
|
|
|
|
|
location coordinate pair when it is sufficiently different in time or
|
|
|
|
|
space from the previous one.
|
|
|
|
|
|
|
|
|
|
There are two parameters associated with resampling fused location in
|
|
|
|
|
the `LOCATIONS` section of the `config.yaml` file.
|
|
|
|
|
`RESAMPLE_FUSED_CONSECUTIVE_THRESHOLD` (in minutes, default 30) controls
|
|
|
|
|
the maximum gap between any two coordinate pairs to replicate the last
|
|
|
|
|
known pair (for example, participant A\'s phone did not collect data
|
|
|
|
|
between 10.30am and 10:50am and between 11:05am and 11:40am, the last
|
|
|
|
|
known coordinate pair will be replicated during the first period but not
|
|
|
|
|
the second, in other words, we assume that we cannot longer guarantee
|
|
|
|
|
the participant stayed at the last known location if the phone did not
|
|
|
|
|
sense data for more than 30 minutes).
|
|
|
|
|
`RESAMPLE_FUSED_TIME_SINCE_VALID_LOCATION` (in minutes, default 720 or
|
|
|
|
|
12 hours) makes that the last known fused location won\'t be carried
|
|
|
|
|
over longer that this threshold even if the phone was sensing data
|
|
|
|
|
continuously (for example, participant A went home at 9pm and their
|
|
|
|
|
phone was sensing data without gaps until 11am the next morning, the
|
|
|
|
|
last known location will only be replicated until 9am). If you have
|
|
|
|
|
suggestions to modify or improve this imputation, let us know.

|
|
|
*Significant Locations Identified*
|
|
|
|
|
|
|
|
|
|
Significant locations are determined using DBSCAN clustering on
|
|
|
|
|
locations that a patient visit over the course of the period of data
|
|
|
|
|
collection.
|
|
|
|
|
|
|
|
|
|
*Circadian Movement Calculation*
|
|
|
|
|
|
|
|
|
|
\"Circadian movement (Saeb et al. 2015) is calculated using the
|
|
|
|
|
Lomb-Scargle method\" (Doryab et. al. 2019)

**Assumptions/Observations:**
|
|
|
|
|
|
|
|
|
|
In Android, `lock` events can happen right after an `off` event, after a
|
|
|
|
|
few seconds of an `off` event, or never happen depending on the phone\'s
|
|
|
|
|
settings, therefore, an `unlock` episode is defined as the time between
|
|
|
|
|
an `unlock` and a `off` event. In iOS, `on` and `off` events do not
|
|
|
|
|
exist, so an `unlock` episode is defined as the time between an `unlock`
|
|
|
|
|
and a `lock` event.
|
|
|
|
|
|
|
|
|
|
Events in iOS are recorded reliably albeit some duplicated `lock` events
|
|
|
|
|
within milliseconds from each other, so we only keep consecutive
|
|
|
|
|
unlock/lock pairs. In Android you cand find multiple consecutive
|
|
|
|
|
`unlock` or `lock` events, so we only keep consecutive unlock/off pairs.
|
|
|
|
|
In our experiments these cases are less than 10% of the screen events
|
|
|
|
|
collected and this happens because `ACTION_SCREEN_OFF` and
|
|
|
|
|
`ACTION_SCREEN_ON` are \"sent when the device becomes non-interactive
|
|
|
|
|
which may have nothing to do with the screen turning off\". In addition
|
|
|
|
|
to unlock/off episodes, in Android it is possible to measure the time
|
|
|
|
|
spent on the lock screen before an `unlock` event as well as the total
|
|
|
|
|
screen time (i.e. `ON` to `OFF`) but these are not implemented at the
|
|
|
|
|
moment.
|
|
|
|
|
|
|
|
|
|
To unify the screen processing and use the same code in RAPIDS, we
|
|
|
|
|
replace LOCKED episodes with OFF episodes (2 with 0) in iOS. However, as
|
|
|
|
|
mentioned above this is still computing `unlock` to `lock` episodes.

and each provides raw sleep data in a different format:
|
|
|
|
|
|
|
|
|
|
> - Sleep level. In `v1`, sleep level is an integer with three

|
There are four heart rate zones: `out_of_range`, `fat_burn`, `cardio`,
|
|
|
|
|
and `peak`. Please refer to [Fitbit
|
|
|
|
|
documentation](https://help.fitbit.com/articles/en_US/Help_article/1565)
|
|
|
|
|
for more information about the way they are computed.
|
|
|
|
|
|
|
|
|
|
Calories\' accuracy depends on the users' Fitbit profile (weight,
|
|
|
|
|
height, etc.).

|
exclude_sleep Whether or not to exclude step rows that happen during sleep
|
|
|
|
|
exclude_sleep_type If `exclude_sleep` is True, then you can choose between `FIXED` or `FITBIT_BASED`. `FIXED` will exclude all step rows that happen between a start and end time (see below). `FITBIT_BASED` will exclude step rows that happen during main sleep segments as measured by the Fitbit device (`config[SLEEP][DB_TABLE]` should be a valid table in your database, it usually is the same table that contains your STEP data)
|
|
|
|
|
exclude_sleep_fixed_start Start time of the fixed sleep period to exclude. Only relevant if `exclude_sleep` is True and `exclude_sleep_type` is `FIXED`
|
|
|
|
|
exclude_sleep_fixed_end Start time of the fixed sleep period to exclude. Only relevant if `exclude_sleep` is True and `exclude_sleep_type` is `FIXED`

|
Active and sedentary bouts. If the step count per minute is smaller than
|
|
|
|
|
`THRESHOLD_ACTIVE_BOUT` (default value is 10), that minute is labelled
|
|
|
|
|
as sedentary, otherwise, is labelled as active. Active and sedentary
|
|
|
|
|
bouts are periods of consecutive minutes labelled as `active` or
|
|
|
|
|
`sedentary`.
|
|
|
|
|
|
|
|
|
|
`validsensedminutes` feature is not available for Step sensor as we
|
|
|
|
|
cannot determine the valid minutes based on the raw Fitbit step data.
